Summary: The Indian summer monsoon is crucial for providing the majority of annual rainfall to the Indian subcontinent and affecting over a quarter of the world's population. Asia is also a significant source of dust, and the interactions between dust and the monsoon are increasingly studied. Dust particles can modulate monsoon circulation and precipitation, while the monsoon can in turn influence dust emissions and deposition.

Summary: In this study, the relationship between the Asian summer monsoon (ASM) and westerlies at different time scales was investigated. The results reveal a long-term decrease in monsoon intensity over the past 4750 years, influenced by orbital solar forcing. Additionally, millennial-scale weak monsoon intervals were observed, showing an antiphase relationship with other paleoclimate records in Asia and southern Europe, but in phase with those in Nordic and Greenlandic regions.

Summary: Studying the interactions between paleoecology and climate variations in semi-arid areas, such as the Songnen grasslands in northeastern China, provides insights into how future vegetation changes and hydrological variations may impact semi-arid ecosystems. This study presents a high resolution palaeoecological dataset covering the past 7300 years and reveals the dynamics of vegetation and water levels in the Dabusu peatlands. By comparing these features with regional climate change, the study suggests that East Asian Summer Monsoon circulations might be the main driving force controlling the regional paleovegetation dynamics and hydrological variations.

Summary: Lakes are important freshwater resources, but they are threatened by eutrophication caused by human activities and climate change. This study examines the ecological response of Dali Lake to climate change and human activity and finds that the lake's ecological status was most stable during the early to middle Holocene. Eutrophication episodes occurred during periods of weakened summer monsoon and enhanced human activities, but the reduction in lake size due to monsoon recession and increased aeolian inputs were identified as more important triggers of lake eutrophication.

Summary: This study examines the impact of the zonal shift of the Asian westerly jet (AWJ) core on the spatial-temporal variability of East Asian summer monsoon (EASM) precipitation. Through Holocene climate simulations, it is found that the eastward shift of the AWJ core is responsible for the changes in summer precipitation in central and southern China. This shift affects the atmospheric circulations and low-level motions, resulting in the observed changes in precipitation. Additionally, differences in land cover between East Asia and central Asia further modulate the movement of the AWJ core.

Summary: Studies on aeolian deposits in Lake Lugu, SW China, reveal that the sediments originated from long-distance dust sources in northern India and the northwest Deccan Plateau over the past 32 kyr. The sediment supply to the lake was influenced by changing vegetation cover in these regions, with deposition rates fluctuating over time.

Summary: This study aims to understand the distribution of NO2, NO, and NOx in the upper troposphere-lower stratosphere (UTLS) within the Asian summer monsoon (ASM) through satellite measurements. The observations show that NO2 levels are relatively low over the ASM during the summer months, while NO and NOx levels are elevated due to low ozone concentrations and cold temperatures. The results are in reasonable agreement with simulations from the Whole Atmosphere Community Climate Model.

Summary: This study on the Holocene climate variations in the Lake Wulanhushao basin in southern Inner Mongolia revealed an increase in moisture levels followed by aridification over the past 10.1 kyr. While pollen data showed expansion of trees, non-pollen proxies indicated a slightly different climate pattern. This suggests the importance of multi-proxy analyses when investigating responses to regional climate variations.

Summary: The interannual variability of the Asian summer monsoon has significant impacts on Asian society. Advances in climate modelling have enabled useful predictions of the seasonal Asian summer monsoon up to approximately half a year ahead, but long-range predictions remain challenging. Using a large ensemble hindcast experiment, researchers demonstrate that a state-of-the-art climate model can predict the Asian summer monsoon and associated tropical cyclone activity more than one year ahead by successfully simulating El Nino-Southern Oscillation evolution and realistically representing subsequent atmosphere-ocean responses in the Indian Ocean-western North Pacific.

Summary: This paper reviews Late Quaternary climatic changes and glacier variability in the Himalaya and East Africa, focusing on the role of Indian Summer Monsoon, East African monsoon, and Westerlies monsoons. The study suggests that the Westerlies monsoon significantly contributed to the Northwestern Himalaya, while the ISM controlled glacier fluctuations in the Western Himalaya during the Late Quaternary.

Summary: This study reports key and widespread late Pleistocene to Holocene tephras from a lake sequence in southern China, providing important potential for dating and synchronizing paleoenvironmental records in East Asia. The extensively distributed tephras enable correlations between tropical Philippines, mainland China, and midlatitude Japan, facilitating future climate studies in the region. The findings highlight volcanic hazards in densely populated East Asia and offer solutions for dating uncertainty in synchronizing rapid climate events.

Summary: The position of the Current Warm Period (CWP) in China's climate history over the past 22,000 years shows that summer temperature and precipitation during this period are lower than in the Early to Middle Holocene, with sensitivity to orbital forcing. While the climate in northern China is more sensitive to nonanthropogenic external forcings, anthropogenic forces have a stronger impact on summer precipitation in Southwest China since the early 20th century.

Summary: The study found a 12-cm-thick dolomite layer formed in Lake Sayram in Central Asia, consisting of calcium-rich dolomite crystals with irregular shapes. It is suggested that the dolomite may have formed under the influence of day and night temperature cycling in shallow lake water due to the local warming trend. This study provides evidence for abiotic dolomite formation at ambient temperature.

Summary: Understanding the mechanisms behind the precipitation pattern in the Asian summer monsoon area is important for reconstructing environmental and hydrological conditions in the past 2000 years. A study on the sediments of Baxian Lake in southern China shows that a transition from dry to humid climate occurred in AD 800-950, followed by extreme drought during the second half of the Medieval Warm Period. Fluctuations between wet and weak drought climates were also observed during the Little Ice Age. The study suggests that the precipitation pattern in southern China differs from that in northern China and India, possibly due to the influence of land-ocean-atmosphere dynamics.

Summary: This study uses luminescence dating techniques to reconstruct the sedimentary history and paleogeography of the Yangtze Delta. The results show that the sedimentary sequences in the paleo-Yangtze incised valley can be traced back to the late Pleistocene. The formation of the basal fluvial sedimentary succession likely occurred between marine isotope stage (MIS) 3 and MIS 2. The study also suggests that the hierarchical incised valley systems in the paleo-Yangtze Delta were likely influenced by late Quaternary sea-level changes and the relict inherited topography from the last glacial period.

Summary: Research has found that the injection of Meltwater Pulse 1A into the North Atlantic weakened the Atlantic Meridional Overturning Circulation and caused severe winter temperature drop in the Northern Hemisphere. This extreme cooling triggered the BOlling warming event and led to the recovery of the Atlantic Meridional Overturning Circulation.

Summary: This study investigated the sediment composition of Lake Tuofengling in northeastern China over the past 25 thousand years and found that the sediments are a mixture of aeolian dust and local volcanic detritus. The aeolian dust component is predominantly from the Mongolia Plateau, likely carried by the East Asian Winter Monsoon. The results suggest that ice sheets and ocean circulation play a significant role in driving the East Asian Winter Monsoon.

Summary: Global warming has led to the desiccation of lakes in arid and semi-arid northern China. The mechanisms behind the fluctuations in water levels in this region are still unclear. This study used luminescence dating techniques to establish the chronologies of sedimentary sequences in Daihai Lake catchment area and examine the late Quaternary history of lake level fluctuations. The results suggest that the variations in lake levels are primarily regulated by monsoonal precipitation, with temperature changes playing a minor role.
